摘要： Embodiments of the present disclosures disclose a method and a system to notify an operator that perception sensors of an autonomous driving vehicle (ADV) need to be recalibrated. In one embodiment, a system perceives a surrounding environment of an autonomous driving vehicle (ADV), including one or more obstacles. The system extracts feature information from previously stored point clouds mapping a three-dimensional surrounding environment of the ADV. The system identifies one or more matching features between the extracted feature information and features of the one or more obstacles. The system determines an average offset distance based on each of the matching features. The system determines an average offset distance distribution based on the average offset distance over a period of time. The system sends an alert to the ADV to alert that the one or more sensors is recommended for recalibration if the average offset distance distribution satisfies a predetermined condition.

摘要： A method for processing three-dimensional scanning data is provided. The method includes acquiring a first coordinate set sequence by a target optical tracker measuring a first target ball group when the target optical tracker is at a plurality of different target positions, and a position of the first target ball group remains unchanged. A second coordinate set sequence is obtained by a laser tracker measuring a second target ball group when the target optical tracker is at the plurality of different target positions, a position of the laser tracker remains unchanged, and a relative position of the second target ball group to the target optical tracker remains unchanged. A target transformation matrix between a coordinate system of the target optical tracker and a coordinate system of the laser tracker is determined based on the first coordinate set sequence and the second coordinate set sequence.

摘要： An integrated system and method for monitoring a workspace, classifying regions therein, dynamically identifying safe states, and identifying and tracking workpieces utilizes semantic analysis of a robot in the workspace and identification of the workpieces with which it interacts, as well as a semantic understanding of entity properties both governing and arising from interaction with other entities for control purposes. These properties may be stored in a profile corresponding to the entity; depending on the implementation, the profile and methods associated with the entity may be stored in a data structure corresponding to the entity “class.” Volumetric regions (e.g., voxels) corresponding to each entity may be tracked and used to implement object methods and/or control methods. For example, machinery may be controlled in accordance with the attributes specified by the objects corresponding to identified entities in a monitored workspace.

摘要： The method for position calibration serves to fuse images of a camera and a LIDAR sensor. The camera records an image of a calibration board, wherein the pose of the calibration board relative to the camera can be determined based on known patterns. The LIDAR sensor records an image of the calibration board, wherein a pose of the calibration board relative to the LIDAR sensor can be determined based on additional reflection regions on the calibration board. Based on both poses, images that are recorded by the camera and/or the LIDAR sensor can respectively be converted into a common coordinate system or into the coordinate system of the other image in the following. Objects that are detected in one image can thereby be verified in another image.

摘要： The present technology relates to an information processing apparatus, an information processing method, a program, a mobile-object control apparatus, and a mobile object that make it possible to appropriately set the accuracy in detecting an object.
An information processing apparatus includes a first object detector that performs an object detection on the basis of first sensor data from a first sensor; a second object detector that performs an object detection on the basis of second sensor data from a second sensor that differs in type from the first sensor; a tracking section that predicts a state of a target object that is a tracking target, on the basis of a result of the object detection performed on the basis of the first sensor data, and on the basis of a result of the object detection performed on the basis of the second sensor data; and a detection accuracy controller that sets a high-resolution range on the basis of the state of the target object that is predicted on the basis of the result of the object detection performed on the basis of the first sensor data, and on the basis of the result of the object detection performed on the basis of the second sensor data, the high-resolution range being a range in which an object detection is performed with a higher degree of accuracy than in a range other than the high-resolution range. The present technology is applicable to, for example, a system used to track a target object around a vehicle.

摘要： A method of operating a coordinate measurement device includes selecting an operating mode on the coordinate measurement device. A first light is emitted from at least one light source of the coordinate measurement device. At least two angles associated with the emitting of the first light are measured. A second light is received with an optical detector of the coordinate measurement device. The second light is a reflection of the first light off of at least one of the retroreflector and the surface. A first distance is determined based at least in part on a mode of the coordinate measurement device that is selected, the emitting of the first light, and the receiving of the second light. Three dimensional coordinates of a point in the environment is determined based on the measuring of the at least two angles and at least one of the first distance and the second distance.
